Application filed November 29, 1901. Serial No. 84,122. (No model.)

To @ZZ whom, it may concern:

Be it known that we, ANDREW GILLIGAN MACOULLOCH, gentleman, residing at11 Palace Mansions, Kensington, and HERBERT DICKINSON, engineer,residing at 2 Camden Gardens, Shepherds Bush, in the county of London,England, subjects of the King of Great Britain, have invented a new orImproved Cash-Register and Till, of which the ro following is aspecification, reference being had to the drawings hereunto annexed andto the reference-numbers marked thereon.

Figure 1 is a front elevation of a machine constructed according to lthepresent invention. Fig. 2 is a similar View, partly in section and withthe front part of the cover removed. Fig. 3 is a plan thereof with partof the cover broken away. Fig. 4 is a side elevation thereof, partly insection and with the zo side of the cover partly removed. Fig. 5 is afront elevation of parts. Fig. G is a side elevation thereof. Fig. 7 isa plan of the inner end of the key-lever and some adjacent coacfingparts, showing the position they assuine when the key-lever is at theextremity of its traverse and has been depressed. Fig. 8 is a similarview, but showing the parts in the position they assume when thekey-lever has been returned to its normal or zero posi- 3o tion andbefore it has been depressed. Fig.

9 is a front elevation thereof, partly in section. Fig. 10 is asectional side View showing the principal working parts of the machine.Fig. 11 is a front elevation, partly in section, illustrating the meansactuated by the key-lever for restoring the parts to their normalpositions. Fig. 12 is asectional front View of parts. Fig. 13 is a planof parts, showing the spring-stud riding upon the edge 4o of thecoacfing disk. Fig. 14 is a similar view, partly in section, showing thespringstud being depressed by the inclined side of the recess in thecoacting disk. Fig. 15 is an elevation of the counting apparatus andcoacting drum. Fig. 16 is a similar but opposite side view of the drum.Fig. 17 is a sectional side view of the gong and coacting parts in theirnormal positions; and Fig. 18 is a similar View, but showing the hammer5o retracted and about to be released.

1n the several figures like parts are indicated by similarreferencenumerals, and Figs. 13 to 1S are drawn to an increased scalewith respect to the other figures of the drawings.

1 represents the base of the machine,whicl1 is formed hollow and isprovided with a drawer or till 2, which is adapted to slide in and outof au aperture located in the front of the base 1, and the drawer 2 isautomatically moved forward or opened at the 'times desired by means ofa coiled spring 3 at one end attached to the base 1 and at the other endto the back of the drawer 2, while said drawer is normally retained inits closed position against the force of the spring 3 by means of adetent 4, which engages the back of the drawer 2. The detent 4 iscarried by the rear end of a frame-like lever 5, mounted with capabilityof rocking upon an axis 6 and acted upon by a spring 8 to normallydepress said rear end and hold the detent 4in engagement with thedrawer, and at its front end said lever is provided with a curved orsegmental bar 7, which is depressed at the times desired and ashereinafter described to withdraw the detent 4, when the drawer willspring open, as indicated-by the dotted lines in Fig. 4.

9 represents the framing of the machine, and mounted with capability ofrevolution in bearings 10, carried by said framing, is a horizontalshaft 11, upon which is xed a metal disk 12, to the outer face of whichis fixed a dial 13 at its periphery and divided figured 0, 5, 10, 15,and so on to 95 to represent cents. Upon the shaft 11 is fixed a beveledpinion 14,with which engagesasegmental rack 15, carried bya quadrant 16,fixed upon the upper end of a vertical shaft 17, mounted in bearings 1Sand 19, and upon the vertical shaft 17 is also fixed a crank 20,furnished with a pin 21. Beneath the crank 2O is loosely mounted uponthe shaft 17 asleeve 22, provided with a lug or offset 23, to which isconnected by a horizontal pivot at 24 a key-lever 25, at its outer endfurnished with a button head or key 26, by the aid of which the lever 25may be laterally traversed and depressed at the times desired.Projecting from the sleeve 22 is a table or platform 27, and pivotallymounted upon the key-lever 25 is a pin or stud 28, which passes througha perfoiation in the platform 27 and at its head is fitted with ascrew-nut 29, between which and the platform 27'is arranged acompression-spring 30, which serves to normally retain the key-lever inits raised position and to lift it after each depression, while a coiledextension-spring 31, connected to the platform 27, and a fixed post 32serves to restore the key-lever 25 to its normal or zero position aftereach lateral traverse.

33 represents the case of the machine, in the front ofwhich is formed acurved slot 34, through which rises the post of the key 26 of the lever25, and at the rear of the slot 34 is provided a segmental rack 35,which is d1- vded and figured in a similar way to the dial 13, and thekey 26 is provided with a finger 36, adapted to enter the notches of therack 35 when the key 26 is depressed. The case 3 3 is at the frontthereof provided with an aperture 37, and the figured disk 13 isarranged at the back of said aperture, so that the gures thereon can oneat a time be exhibited thereat, and thus by laterally traversing thekey-lever 25 until the finger 36 is opposite that notch of the rack 35corresponding with the amount to be registered the disk 13A will throughthe key-lever 25, crank-pin 21, vertical shaft 17, segmental rack 15,and pinion 14, as shown more particularly at Figs. 3, 5, 7, and 10, becorrespondingly rotated, so that it will exhibit the correspondingamount at the aperture 37 of the case, and by depressing the key 26until the nger 36 reaches the bottom of said notch -said amount will beregistered, as hereinafter described, and at the same time the key-lever25 will by acting upon the segmental bar 7 of the lever 5 withdraw thedetent 4 and permit the drawer 2 to open under the inuence of the spring3, giving access thereto for the deposit therein of' the purchase moneyand for the purpose of obtaining change, if necessary, and the drawer2is afterward closed by hand. Upon releasing the key 26 the key-lever 25will by the springs 30 and 31 be restored to its normal orzero positionclear of the segmental bar7, as shown at Fig. 3; but the dial 13 willremain locked with the amount exposed at the aperture 37 by thefollowing means until certain other operations have been performed, ashereinafter described.

Upon the horizont-al shaft 11 is fixed a ratchet-wheel 33, with whichengages aweighted pawl 39, mounted upon an axis of motion 40 andprovided with a tail 4l, and the tail 41 of the pawl 39 is acted upon byan arm 42, xed to a vertical rod 43, which is formed with a piston-likeenlargement- 44, working in a cylinder 45 against a spring 46, and thelower end of which rod 43 is provided with a cranked arm 47, terminatingina foot or platform 48, over which the key-lever 25 rests suspended inits normal position, so that by depressing the key 26 the key-lever 25will in turn depress the foot 48 and through the rod 43 and arm 42 tripthe pawl 39 and permit the dial 13 to return to its zero position 11nderthe influence of a spring 49, acting upon the segment 1G. Theregistration of the amount of the purchase is effected concurrently withthe rotation of the dial 13 in the traverse of the key-lever 25, ashereinafter described, and the dial 13 is, as hereinbefore described,held by the pawl 39 until the keylever 25 h-as been restored to its Zeroposition and depressed, and in order to prevent possible fraud bytraversing and depressing at some point in its traverse the key-leverwithout rotating the dial, but so as to sound the alarm-bell,hereinafter described, and open the drawer, a weighted lever 50 isemployed, which is pivotally mounted at 51 upon a bracket 52 and isprovided with a notch 53, adapted to engage the key-lever 25 in its zeroposition, while it is formed with an inclined nose 54, so that it may bedepressed by the key-lever 25 as it returns to zero, when said notch 53will engage and lock the keylever 25 and prevent its being traversed. Inorder to release the key-lever 25 at the proper timethat is to say,after the return to zero of the dial 13-the crank-pin 21 is providedwith a prolongation 55, which in the return traverse thereof with thedial 13 engages the inclined nose 54 of the locking-lever 50, therebydepressing and holding depressed said lever 50 until the next traverseof the key-lever 25. As an additional precaution to prevent fraud a diskis fixed upon the shaft 11 at the rear of the dial 13 and isprovidedwith a depression 61 in the face thereof, and the pawl 39 is providedwith a coacting springstud 62, which enters said depression, but in thetraverse of the key-lever 25 and corresponding rotation of the dial 13is compressed and rides against the face of said disk; but upon thekey-lever being restored to its zero position and depressed, therebylifting the pawl 39, the stud 62 is raised above the edge of the disk 60and springing forward rides upon the edge thereof, thereby keeping thepawl 39 out of engagement with the ratchet-wheel 33 until the dial 13has returned to its zero position, when the stud 62 will drop into thedepression 61 of the disk 60 and permit the pawl 39 to fall intoengagement with the ratchet-wheel 38.

In order to arrest the dial 13 in its Zero position as it returnsthereto under the inliueuce of the spring 49, acting upon the segment16, and also to prevent the dial 13 rebounding, and thereby giving falseindications, the disk 12 is provided with a rearward projection 63,which comes against the lower jaw 64 of a forked or notched stop plateor lever 66, mounted upon an axis of motion 67 and provided with acounterbalance or pendulous tail 63, which strikes against a stop 69, bywhich means the upper jaw of the forked stop is caused to momentarilyswing forward and engage the projection 63 of the disk 12, thuspreventing IIO any rebounding action ofthe dial 13, and said jaw 65after performing this work is immediately thrown out of engagement againwith the projection 63 by gravity.

The dial 13 works synchronously with the key-lever in its traverse-thatis to say,

` whicheverlgure or number of the rack indicating the amount of thepurchase the key-lever 25 is traversed to the corresponding figure ornumber upon the dial 13 will appear atthe aperture 37 of the case-and inorder to register this amount the following arrangement of parts isemployed:

Loosely mounted upon the shaft l1 is a drum 70, the periphery of whichis divided and iigured in a similar manner to the dial 13, and this drumis rotated synchronously with the dial 13 during the traverse of thekey-lever 25 by means of a ratchet-wheel 7l, Xed upon the shaft ll,which engages a pawl 72, carried by the drum 70, and this arrangement atthe same time permits the drum 70 to remain stationary during the returnmovement to zero of the dial 13, and in order to prevent any back actionof the drum 70 a ratchet-wheel 73 is fixed to the bracket lO, formingthe rear bearing of the shaft ll, and a pawl 74, carried by the drum 70,engages the same.

Upon the periphery of the drum 70 is a finger 75, and in connectiontherewith is arranged an ordinary counting apparatus 7G, provided withthe usual star-wheel 77, which is adapted to be advanced one tooth at atime by a moving object in the manner well known, and the finger 75 ofthe drum 70 once in every revolution of said drum engages the starwheel77 and rotates it the distance of one tooth. The counting apparatus 76is provided with a dial having` three apertures at which appear figuresindicating the number of units, tens, and hundreds of dollarsregistered, while the fractions or cents can be read olf upon the drum70,' a stationary pointer 78, carried by the counting apparatus, beingemployed to indicate the actual division upon the drum 70 containing theligures requiring to be read, and in order to enable a View to beobtained of the counting and registering apparatus the case is providedwith a door 79, preferably secured by means of a lock and key. j

It is desirable that the registration of eachamountandtheopeningofthedrawerZshould be accompanied by an audibleindication, and for this purpose a bell or gong 8U is employed which isprovided with a hammer Sl, carried by a bell-crank 82, mounted upon anaxis of motion S3 and actuated by a spring S4, and this hammer Sl isretracted and released at each depression of the key-lever 25 toregister the amount of a purchase by means of a rod 85, at its lower endpivotally connected to the rear end of the lever 5 and at its upper endworking in a guide SG, which it very loosely tits, said rod beingprovided with a tooth or projection S7, adapted to iirst engage theshort arm of the bell-crank 32 and retract the hammer Si and then toslip past the same, permitting the spring 84 to exert its iniiuence andcause the hammer to sound the bell, and

lby reason of the spring 84E being attached to the rod 85 the tooth 87is enabled to slip past the bell-crank in the return movement of saidrod.

It will be understood that the details of construction of the machinemay be to some eX- tent varied without departing from the spirit of theinvention.
